Question

我是EJB的新手。

我正在尝试使用JBoss 7.1测试一个简单的EJB项目。但测试抛出异常：

javax.ejb.EJBException：无法使用工厂实例化容器 [] at javax.ejb.embeddable.EJBContainer.createEJBContainer（EJBCont ainer.java:97）at javax.ejb.embeddable.EJBContainer.createEJBContainer（EJBCont ainer.java:75）在com.pack.HelloTest.test（HelloTest.java:17）at at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method）at sun.reflect.NativeMethodAccessorImpl.invoke（未知来源）at sun.reflect.DelegatingMethodAccessorImpl.invoke（未知来源）at java.lang.reflect.Method.invoke（未知来源）at org.junit.runners.model.FrameworkMethod $ 1.runReflectiveCall（ FrameworkMethod.java:47）at org.junit.internal.runners.model.ReflectiveCallable.run（REFL ectiveCallable.java:12）at org.junit.runners.model.FrameworkMethod.invokeExplosively（FR ameworkMethod.java:44）at org.junit.internal.runners.statements.InvokeMethod.evaluate（ InvokeMethod.java:17）at org.junit.runners.ParentRunner.runLeaf（ParentRunner.java:271）at at org.junit.runners.BlockJUnit4ClassRunner.runChild（BlockJUnit 4ClassRunner.java:70）at org.junit.runners.BlockJUnit4ClassRunner.runChild（BlockJUnit 4ClassRunner.java:50）at org.junit.runners.ParentRunner $ 3.run（ParentRunner.java:238）at org.junit.runners.ParentRunner $ 1.schedule（ParentRunner.java:63）at at org.junit.runners.ParentRunner.runChildren（ParentRunner.java:236）at at org.junit.runners.ParentRunner.access $ 000（ParentRunner.java：53）at at org.junit.runners.ParentRunner $ 2.evaluate（ParentRunner.java：229）at at org.junit.runners.ParentRunner.run（ParentRunner.java:309）at at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.r un（JUnit4TestReference.java:50）at org.eclipse.jdt.internal.junit.runner.TestExecution.run（测试 Execution.java:38）at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTe sts（RemoteTestRunner.java:467）at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTe sts（RemoteTestRunner.java:683）at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run（R emoteTestRunner.java:390）at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main（ RemoteTestRunner.java:197）

这是测试：

package com.pack;

import static org.junit.Assert.*;

import java.util.Date;

import javax.ejb.embeddable.EJBContainer;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import org.junit.Test;

public class HelloTest {

    @Test
    public void test() throws NamingException {
         EJBContainer container = EJBContainer.createEJBContainer(); // line 17, throws javax.ejb.EJBException

          // Note that global naming isn't working yet.
          InitialContext ctx = new InitialContext();
          Hello bean = (Hello) ctx.lookup("HelloBean/local");

          String now = new Date().toString();
          String actual = bean.sayHello(now);

          assertEquals("Hello " + now, actual);

          container.close();
    }
}

Project有一个bean HelloBean：

package com.pack;

import javax.ejb.LocalBean;
import javax.ejb.Stateless;

/**
 * Session Bean implementation class HelloBean
 */
@Stateless
public class HelloBean implements Hello {

    public String sayHello(String name) {
        return "Hello " + name;
    }

}

这是界面Hello：

package com.pack;

public interface Hello {
    String sayHello(String name);
}

你能告诉我如何解决这个错误吗？
